Wilson Combat gave me a chrome silicon firing pin spring, but the BUSA said said they've never heard of the OEM one failing, but as long as I was in there, I might as well replace it with a new one.
Game plan is to remove the extractor first, and then the firing pin block. I've got the right punches, etc., and I'll re-stake the extractor pin after I replace it.
If tomorrow's another snow day, I'll probably do it then.
Best, Jon
